Why Practice CGBSE Class 10 Science Previous Year Question Papers?
For students appearing in the CGBSE Class 10 board exams, Science is a highly conceptual and scoring subject that can dramatically improve your final board percentage. Because the Chhattisgarh Board strictly adheres to the SCERT syllabus, the exam format and critical questions are highly predictable.
By practicing CGBSE Class 10 Science previous year question papers, students quickly notice that specific chemical reactions, physics numericals (like lens and mirror formulas), and biology diagrams (like the human heart or nephron) repeat almost every year. Practicing these papers builds your time-management skills and ensures you don’t lose marks on step-marking in numericals.
Below, you will find our curated archive of over 70 official CGBSE Class 10 Science question papers spanning from 2012 to 2026. This includes main board exams, half-yearly papers, quarterly tests, and official blueprints—all available as safe, one-click PDF downloads.

Blueprint & Section-Wise Weightage for Class 10 Science
Understanding the chapter-wise weightage allows you to prioritize high-yield sections and manage your study time perfectly.
| Section / Unit | Approximate Marks |
|---|---|
| Chemical Substances (Nature and Behavior) | 25 Marks |
| World of Living (Biology) | 20 Marks |
| Natural Phenomena (Light & Optics) | 15 Marks |
| Effects of Current (Electricity & Magnetism) | 10 Marks |
| Natural Resources / Environment | 05 Marks |
💡 Key Insight: The Chemistry and Physics (Light/Electricity) sections carry the heaviest weightage. Most of the 5-mark and 6-mark long questions (with internal choices) are pulled from these units, specifically focusing on numericals and reactions.
Paper Pattern & Typology of Questions
The CGBSE Class 10 Science board paper tests conceptual understanding, analytical thinking, and diagrammatic representation:
- 1-mark Questions (Objective/MCQ): 10-15 Questions based on SI units, valency, and simple biological facts.
- 2-mark & 3-mark Questions (Short Answer): Direct questions requiring clear definitions, differences (e.g., Metals vs Non-Metals), and balanced chemical equations.
- 5-mark & 6-mark Questions (Long Answer): These questions almost always include internal choices. Expect detailed diagrams (Human Eye, Digestive System) or a physics numerical combined with a theoretical definition.
⚠️ Step-Marking Rule (CGBSE): The board strictly follows step-marking. In Physics numericals, writing the given values and formula earns you a mark even if the final calculation is wrong. In Biology, a neat, labeled diagram can secure partial marks even if the theory explanation is weak!
Expert Preparation Strategy for CG Board Class 10 Science
To cross the 90+ threshold, implement these actionable study strategies into your daily routine:
- Master the Diagrams: Draw a list of the top 10 biological and physical diagrams (Heart, Brain, Nephron, Motor, Generator, Eye). Practice drawing them clearly with a pencil and label them properly.
- Reaction Cheat Sheet: Create a single page containing all the named chemical reactions (Esterification, Saponification, Oxidation/Reduction) with their balanced equations. Review this daily.
- Nail the Numericals: Do not skip the Light and Electricity chapters. Memorize the sign conventions for spherical mirrors/lenses and Ohm’s Law formulas to easily secure 8-10 marks.

Frequently Asked Questions (FAQs)
Is the CGBSE Class 10 Science syllabus reduced for this year?
The CGBSE occasionally removes specific chapters from the textbook. Always check the latest circular on the official board website (cgbse.nic.in) for the updated curriculum. However, core concepts like electricity, light, and chemical reactions remain unchanged, making these past papers incredibly valuable.
How many years of Science papers should I solve?
For optimum results, we recommend solving at least 5 to 7 years of CGBSE Science papers. This helps you build problem-solving speed for physics numericals and locks in the formats for biology diagrams.
Are these papers available in Hindi or English medium?
The CGBSE provides bilingual question papers for Science subjects. The PDFs available for download on this page contain the mathematical problems and theory questions printed in both Hindi and English mediums.
